The LT-III X-ray and gamma radiation dose rate meter is a multifunctional portable dose rate meter that uses a built-in high-sensitivity GM counter tube as a detector to measure X-ray and gamma radiation, and can also be used as a radiation monitoring instrument. It has multiple alarm and recording functions, and can set 1000 address numbers to automatically measure and record the average dose rate. Finally, the recorded data is transmitted to the upper computer (computer) through an infrared communication system for statistical processing, and can also be queried separately. Due to its small size, light weight, and easy portability, it can also be used for personal dose monitoring. Therefore, it is highly suitable for personal dose monitoring, radiation field investigation, and emergency radiation measurement in nuclear facilities, nuclear radiation technology application departments, scientific research units, military and environmental protection systems.
